Over the years, the DARPA Challenges in the United States have galvanized interest in autonomous cars, making them a real possibility in the mind of the public, but autonomous and unmanned vehicles have been increasingly employed in many roles on land, in the water, and in the air. Military applications have received a great deal of attention, with weaponized unmanned aircraft (drones) being the most prominent. However, unmanned vehicles with varying degrees of autonomy already have many civilian applications. Some of these are quite familiar (such as the Roomba autonomous vacuum cleaner), while others remain largely out of the public eye (such as autonomous farm equipment). Additional applications and more capable vehicles are rapidly coming to the markets in the years ahead. This book examines a number of economically important areas in which unmanned and autonomous vehicles, also understood here as autonomous technologies, are already used or soon will be.

This book explains how mechanical material behavior relates to the design of structural machine components. The major emphasis is on fatigue and failure behavior using engineering models that have been developed to predict, in advance of service, acceptable fatigue and other durability-related lifetimes. Information covers broad classes of materials used for high-performance structural applications such as aerospace components, automobiles, and power generation systems. Coverage focuses on metallic materials but also addresses unique capabilities of important nonmetals.

Increased demand for gears to transmit more power through smaller, lighter, quieter, and more reliable packages that must operate over a wide range of service conditions, has made the design and manufacture of gears much more complex. Gears manufactured from certain steels are found to meet these demands, and become especially effective when heat treated and finish machined for high geometric accuracy. However, distortion of the gear after heat treatment offers the gear engineer a challenging opportunity not only in ensuring a high quality product but also in controlling manufacturing costs. Heat Treatment of Gears is designed to provide the gear design engineer with a better understanding of heat treatment and its effects on gear quality and performance, especially as these considerations are critical to ensuring that the gears perform satisfactorily under anticipated service conditions.

The emerging technology of very inexpensive inertial sensors is available for navigation as never before. This book lays the analytical foundation for understanding and implementing the navigation equations. It starts by demystifying the central theme of the frame rotation using such algorithms as the quaternions, the rotation vector and the Euler angles. After developing navigation equations, the book introduces the computational issues and discusses the physical aspects that are tied to implementing these equations, also explaining alignment techniques. Introduction to Modern Navigation Systems offers an efficient algorithm for polar navigation. It also shows how to enhance the performance of the inertial system when aided by the Global Positioning System.

Functioning as an introduction to modern mechanics principles and various applications that deal with the science, mathematics and technical aspects of sheet metal forming, Mechanics Modeling of Sheet Metal Forming details theoretically sound formulations based on principles of continuum mechanics for finite or large deformation, which can then be implemented into simulation codes. The forming processes of complex panels by computer codes, in addition to extensive practical examples, are recreated throughout the many chapters of this book in order to benefit practicing engineers by helping them better understand the output of simulation software.

Mobility is in crisis, but few seem aware of the full extent of it. This book shows that for a genuinely sustainable transport future, far more radical change - affecting many aspects of society - is needed. This book brings together a range of views representing both leading-edge thinking and best practices in the mobility sector, with the individual expert contributions framing a broader vision of future mobility. It is necessary to move beyond the technology of new cars to confront the challenges of institutional, cultural, and social change required for increased sustainability. This book breaks through the conventional boundary between engineering and the social sciences, and the contributors represent both sides of this divide, combining economists, engineers, geographers, designers, and others.

This book provides a fascinating glimpse into a vital material that we may take for granted today. Stainless steel, called “the miracle metal” and “the crowning achievement of metallurgy” by the prominent metallurgist Carl Zapffe, is a material marvel with an equally fascinating history of people, places, and technology. As stainless steel nears the 100th anniversary of its discovery, this book is a fitting perspective on a vital material of our modern life, and it is the first book that captures the unfolding excitement and innovations of stainless steel pioneers and entrepreneurs. Amply illustrated with photographs, the book also includes a timeline that lists more than 450 important facts and events related to stainless steels technology and applications.
